Abstract:
A method and an apparatus for connecting a coaxial (or a micro coaxial) cable to the bottom side of a printed circuit board (PCB) in order to improve signal integrity of a test circuit. A coaxial or a micro coaxial cable is directly connected to a coaxial cable to the bottom sides of pads located on an exterior later of the PCB.
Abstract:
A ceramic wiring board that includes a ceramic insulator and a via-conductor. The ceramic insulator includes a crystalline constituent and an amorphous constituent. The via-conductor includes a metal and an oxide. The crystalline constituent and the oxide include at least one metal element in common. A tubular region having a thickness of 5 μm adjoins and surrounds the via-conductor and has a higher concentration of the metal element than the ceramic insulator.
Abstract:
There is provided a heat dissipating substrate including: a base substrate having a first through hole formed therein; a first substrate disposed on an upper end portion of the base substrate and including a second through hole having a diameter smaller than that of the first through hole; and a heat dissipating pad disposed on an upper end portion of the second through hole. In addition, a flow phenomenon of a thermal conduction member (lead) may be reduced using the thermal conduction member by forming a second through hole smaller than a first through hole.
Abstract:
A substrate package includes a woven fabric having electrically non-conductive strands woven between electrically conductive strands including wire strands, co-axial strands, and/or an inductor pattern of strands. The package may be formed by an inexpensive and high throughput process that first weaves the non-conductive strands (e.g., glass) between the conductive strands to form a circuit board pattern of conductive strands in a woven fabric. Next, the woven fabric is impregnated with a resin material to form an impregnated fabric, which is then cured to form a cured fabric. The upper and lower surfaces of the cured fabric are subsequently planarized. Planarizing segments and exposes ends of the wire, co-axial, and inductor pattern strands. Since the conductive strands were formed integrally within the planarized woven fabric, the substrate has a high mechanical stability and provides conductor strand based electrical components built in situ in the substrate package.

Provided are coaxial waveguide microstructures. The microstructures include a substrate and a coaxial waveguide disposed above the substrate. The coaxial waveguide includes: a center conductor; an outer conductor including one or more walls, spaced apart from and disposed around the center conductor; one or more dielectric support members for supporting the center conductor in contact with the center conductor and enclosed within the outer conductor; and a core volume between the center conductor and the outer conductor, wherein the core volume is under vacuum or in a gas state. Also provided are methods of forming coaxial waveguide microstructures by a sequential build process and hermetic packages which include a coaxial waveguide microstructure.

Abstract:
The present disclosure is directed to orientation-independent device configuration and assembly. An electronic device may comprise conductive pads arranged concentrically on a surface of the device. The conductive pads on the device may mate with conductive pads in a device location in circuitry. Example conductive pads may include at least a first circular conductive pad and a second ring-shaped conductive pad arranged to concentrically surround the first conductive pad. The concentric arrangement of the conductive pads allows for orientation-independent placement of the device in the circuitry. In particular, the conductive pads of the device will mate correctly with the conductive pads of the circuitry regardless of variability in device orientation. In one embodiment, the device may also be configured for use with fluidic self-assembly (FSA). For example, a device housing may be manufactured with pockets that cause the device to attain neutral buoyancy during manufacture.
